2.2.1 SIM/UIM Card
TG452 supports normal SIM/UIM only, so if you’re using a Micro SIM or Nano SIM card,
you may need to use a Micro SIM or Nano SIM to Normal SIM adapter.
Make sure your router is powered off, then use a needle object(such as a pen) to push the
button near the SIM/UIM card holder, it will flick out immediately. Put the SIM/UIM card to
card holder with chipset upside, insert it to router and make sure it’s tightly matched.
Warning: Never install SIM/UIM card when router is powered on.
